I'm interested in buying this, since my iphone looses battery too fast and also this has a bigger memory.
I own a pair of harman kardon NC. Considering it's a portable 3 in 1 source/dac/amp, do I need something better, like adding another amp to it?
Also, so i don't start another thread, I've found a promo package consisting of HD650 and Burson HA-160 amp for 795 €(in my country, I know compared to USA is expensive).
Another one is HD800 and Burson Conductor for 2300€, but that's for another day, year, 5 years.
